What is a Solar Backpack?
With the daily advancement in technology, we have become so attached to various gadgets that you can’t imagine living a minute without them. Smartphones, tablets, and laptops are among the many devices that have changed our way of living, and therefore, most people hate it when their battery dies.
Whether you are going for a short outdoor stroll or a few days of adventure, solar backpacks will ensure that your gadgets stay functional.
Due to the existence of numerous brands of solar backpacks available today, I have prepared a comprehensive list of the best solar backpacks to choose from.
But before that, let us understand what solar backpacks are and how they operate.
Just as the name suggests, a solar backpack is a rucksack that comes with a small, built-in solar panel and batteries. The solar cells help to convert energy that comes from sunlight into electricity.
The electricity is then stored in the batteries and is used to charge portable electrical devices such as phones, flashlights, and more.
Solar backpacks vary in storage volume, battery capacity, solar panel output, among other features. With the advancement in technology, different companies are introducing more and more features into these backpacks.
All this gives the user a wide range to choose from and ensures quality due to the stiff competition.
How Solar Backpacks Work
A solar backpack will, in most cases contain flexible monocrystalline solar cells, a battery, plugs, charge controller, light bulbs, and cords. When sunlight hits the solar panel, the cells convert the sunlight energy into solar power, which it then stores in the in-built battery.
The packs offer the user a max power of up to 120Wh in a day, which can provide power gadgets with up to 300W rating.
Solar backpacks can be employed in disaster relief, international aid, field research, and emergency power, among other situations. No matter the case, as long as there is sunlight, your devices will be on.
What to Consider when Buying a Solar Backpack
Before paying for that solar backpack, there are several things you ought to consider, and which will help you make the right choice.
Based on your requirements, here are these factors you should not fail to check.
Different backpacks will have varying charging voltages. You don’t want to buy something with too little voltage that it can’t charge your devices. For example, most electronic devices, like phones, mostly require 5V to charge. Therefore, anything below that might give you unnecessary challenges when you want to charge.
For this reason, you should look for a backpack that has a voltage specification greater or equal to your charging needs. This way, you can comfortably charge any devices that you carry. Use this guide on solar battery charging basics to learn more.
Although mostly confused with voltage, we measure power usage in milliampere-hours (mAh), especially for small appliances. It is the amount of power that your gadgets need to charge. In most cases, this is indicated on the technical specs part of the device.
For example, a 2500 milliampere-hour solar backpack, will charge a device of 1000 milliampere-hour gadget for 2 and a half times without recharging the solar pack. You should check this against the mAh requirement of your devices.
The more the USB ports a solar backpack has, the better. A solar pack with more than one USB port is great as it allows you to charge more than one device simultaneously. Although most will come with only one, there are a few that have two, but which cost a bit higher.
If you want to carry multiple devices for your trip, better get that backpack that will allow multiple charging. Why carry a dead phone while charging your flashlight or GPS navigator? Be able to charge them both.
Since solar backpacks are not that cheap, you should ensure that the cost matches the durability and the features of the backpack. A solar backpack should be made of a material that lasts long, and that will withstand those extreme weather conditions.
Both the solar panel system and the bag itself, ought to be durable enough to ensure that you enjoy your outdoor travel, especially in harsh conditions.

The much that you have planned to spend will significantly affect what you buy. With solar backpacks, the price is mostly dependent on the brand, and the features included on the backpack. Solar backpacks from known brands tend to be more expensive, as well as the ones with multiple features.
Depending on your budget, you should carefully evaluate all the pros and cons of certain brands before coming into a conclusion to buy.
